I have copied and pasted the information on the different types of Buddhas which is presented in the article from the link above. There are suggestions on where to put each type of Buddha in your home, based on Feng Shui principles.

Meditating Buddha
This statue style most commonly found in Buddhist altars in the home. These statues typically render Buddha in a sitting position with both hands in a meditative position called “Cosmic Mudra. The hands overlap each other. The left hand is placed on top of the right one so the thumb tips touch to form an oval, symbolizing the turning of one’s attention inward.

The statue should face the east direction since the Buddha meditated on the sun rising in his search for enlightenment.

Rubbing his belly will bring greater good luck and fortune.

Laughing Buddha
In western culture, the laughing Buddha is probably the most widely recognizable and used. It’s also known as the good luck, prosperity or abundance Buddha. It depicts Buddha in his later years as happy and with a large belly from an abundant lifetime. He’ll either be in a sitting position or standing with his hands over his head supporting a real or imaginary Ru-Yi pot (vessel or bowl of plenty).

This statue is affectionately dubbed Happy. It’s tradition to rub his belly to ensure even greater luck is bestowed upon you. Place this statue in your personal wealth corner or southeast sector of your home. It’s great for an office on the north wall facing those who enter.

Other variations include:

Laughing Buddha with children at his feet: Place in west sector (descendants) of garden facing your home. Also use in same sector inside your home.
Traveling Buddha: A variation of the laughing Buddha as a monk features a cotton-sack over one shoulder or tied to a stick. He holds a wealth ball in his other hand. It is an excellent choice if you travel for work. Place in your office in north sector.
Spiritual Journey Buddha: This is another version of the Traveling Buddha. He carries a gourd (wu-lou) of enlightenment suspended from a stick while holding a fan in his other hand and wears a prayer bead necklace. Place in northeast sector (education) or southwest (love and relationships).
Blessing Buddha
The Blessing pose depicts Buddha bestowing fearlessness (upper hand gesture) and compassion (lower hand). Good areas inside the home for this statue include the office and den. You can apply this as a cure for any area inside or outside your home that suffers from weak or afflicted chi due to flying star placement.

Teaching Buddha
Known as Dharma Chakra Buddha, the Teaching Buddha statue is in a sitting or standing position. The most popular is the sitting pose, since this is the position the Buddha assumed when teaching. This is an important period in the Buddha’s life. It symbolizes his sharing of the knowledge he’d gained after his enlightenment in the deer park, Sarnath, located in Uttar Pradesh, India with his disciples.

Since the Buddha’s teachings came from his heart, the both hands are in front of his chest. The index fingers and thumbs touch to form a circle, representing his teaching of the Wheel of Dharma (union of wisdom and method). The other three fingers of both hands always remain extended.

This is an excellent choice for the northeast (education) sector of both inside your home or office and your garden.

Some statues depict the thumb touching the ring finger instead of the forefinger. This changes the meaning to one of good fortune. This style can be placed in the north sector (career) or southeast sector (wealth).

Long Life Buddha
This Buddha sits with the bag of blessings by his side or may hold the bag in his lap. In one hand, he cradles a wealth ball raised in front of him and a Ru-Yi pot in his other hand. Place in your home or garden in the east (health), west (children, descendants) or southeast (wealth) sector. You can also place it in your office in these directions.

Happy Home Buddha
The seated Happy Home Buddha holds a parasol over his shoulder. Place inside and outside your home in the southwest sector (relationships).

Earth Buddha
Also known as the Calling Earth to Witness, the Earth Buddha sits on the ground with his right hand extended so his fingers point to the earth beneath him. This statue honors the time when Buddha was repeatedly tempted by the demon, Mara, but resisted and finally reached enlightenment.

You can place this statue in any sector inside or outside your home that you’re being tempted to reject. If you’re having difficulty in a relationship, place it in the southwest sector to bolster your resolve and commitment. If you’re becoming complacent at work, put this in the north sector (career) to strengthen your dedication to your job.

Reclining Buddha
Buddha awaits his transition from this life to death, viewed as a mere transition into a different state of being. if you’re in a transition period, this is a good choice for inside your home or in a garden.

Place in the sector that represents the area of your transition. For example, place in north sector of home or office if changing jobs. If a relationship has ended, place in southwest sector. If you’re a new empty nester, place statue in west sector to ease this life-changing transition.
