Any terrible plays here pre-flop?

[Insistent_]

Okay or bad - and a little comment on each one would be nice. [img]/images/graemlins/cool.gif[/img]

Game is low stakes, 0.25/0.50. 5-handed if nothing else is stated.
200 BB stacks.

1. 8897. 1 limp and I limp on the button. Okay?
2. KQ98 ds 4-handed. 1 limp. I raise pot. Okay?
3. J998 ss. 1 limp. I limp on the button. Okay?
4. TT44 1 limp. I limp on the button and my intention is to fold to a pre-flop raise. Stacks are 50bb in this case. Okay plan?

Thanks.
