Thanls for this imagcq.
Here is my stab at them.
1) Plant model on joint pole (4/4)- TREE FERN?
Model “T” on joint – reefer + pole – N gives Tree fern – plant?
2) Old flesh within 200 yards is in reach (4/2/4)- COME-AT-ABLE?
Old – O with flesh – meat, within Cable – a length of 200 yards gives C o me at able- in reach?
3) Be careful to arrive before effortless work that doesn't bother you. (4/4/4/2)- EASY COME EASY GO?
Easy- be careful + arrive- come + effortless- easy+work – go gives Easy come easy go – that doesn’t bother you?
4) Dance party's seen in term once again (7)- RELABEL?
Party- Lab within dance – reel gives Re lab el, to “term once again”?
This gives TNCEEORL – ELECTRON?
