need help with the sentences

Hi, say there are a group of children playing before a tree, and I write some sentences about what they do.

Some of them dance and sing; some climb up the tree to see further; some takse photos while others eat.

I mean to say their activities include dancing, singing, climbing, photo-taking and eating. Have I clearly described so above? I lack in confidence in using 'the'. Should I actually use 'the others' than 'others' in the last sentence? Thank you for your time in advance.

If you say "others", that means "some of the others". If you say "the others", that means "all of the others".

Thanks.

I need help on another sentence. I'm trying to describe a girl who likes pretending to be nice and positions herself as a straightforward person hating 'fake' people. Does this sentence serve the purpose?

She's fake while calling others the same thing.

<<She's fake while calling others the same thing.>>

If you're saying that, or using it informally that's fine - as your body language and other things will give cues as to what you mean.

But if you want to write this in, say, an essay then

'She acts fake, while condemning others for doing the same' is a fuller way of saying it.
