A few questionable hands

Live home game, .10/.20 blinds. Original buy in : $5
-7 handed

(I will post hand results...and they're in no particular order)

Hand 1 --------"Preflop with queens"--------------------

Hero: $13
Villain (button): $25
UTG: $1.60
BB: $18.00

SB posts BB post, UTG goes all in ($1.60)
Hero looks at QQ, raises to $4.45

Villain makes a comment as I raised "What would you raise 2.85 with?" and showed genuine concern. I immediately took AA out of his hand range (he wouldn't say a word with AA, he would just "sigh" and move all his chips in) and put him on KK, AK, or possible JJ. After a deliberation period, he shrugs and waves his hand all in.
