They're all fine.

Adverbs, like "still" can be placed many places in a sentence.
But which sentence should I use?
What is the complete sentence?
"The pine is able to hold two washers (80 grams...and...(pick one of the sentences above that best fits)"
This is probably the best:

"...and still is able to hold more..."
