They're not legless, they're folded legs.
The first picture is a dc converter. They are cmb rate for most yards
Picture 2 the loose cap chip is a 486 class. The one on the board I'm not sure what Chris will do, but you can pry it loose for 486 rate.
3rd looks like a mix of 8086 and 386/486 rate. The green ones are green fibre without metal. The ceramics with no gold cap and gold pins go Pentium /mac ceramic. the ceramics with a cap and silver pins go ibm/via gold cap. Finally the ceramics with silver pins and no cap go standard ic rate.
4th see above 3rd pic reply.
5th looks like standard ics.
The board with the inverted memory controllers will go gold cap chip board, even though you can't see the caps. However most of those controllers will pop loose for you. The majority will go 8086 or 386/486 class.
And lastly I'm not seeing what you mean by T chips.
