I don't have a Familitchi so this might not be correct.
These are the icons:
1. Check meter (hungry/happy screen with five hearts instead of four, family name/gender/generation, bonding percentage and family type, all character's species and role in the family)
2. Feeding (meal and snack with multiple sub-options)
3. Toilet (same as normal but when they need the loo they move back and forth in a line)
4. Games (TV surfing, tea time, golf putt and shoe match- the last two games are unlocked on the second generation)
5. Communication (v5, Special and PC for any Family Tamagotchi outside of Japan- Famitama, DVD, PC and Special for any Famitama in Japan)
6. Training/Care (three random options for when your Tamagotchi are bored)
7. Item box (all your items and medicines here)
8. Gotchi TV (TV shopping replaces the shop, Dating Channel replaces the Matchmaker and Travelling Channel replaces the pause function believe it or not)
9. Tamagotchi notebook (friends and memories)
10. Attention sign (same as all other versions)
And here's how to get different families (your family might have to have full bonding percentage to get a special family):
Your Mametchi + Someone's Chantotchi = Mame Family
Your Memetchi + Someone's Mumutchi = Meme Family
Your Kuchipatchi + Someone's Yonepatchi = Kuchi Family
Your Furawatchi + Someone's Sukatchi = Violet Family
Any adult and too much food = Large Family
Any adult and too little food = Petit Family
Any adult and not happy enough= Ninja Family
A mix of characters = Blended Family
