Will this get sun cream stains out?

Sorry, I’ve got no idea about sun cream stains - I’d be far more likely to soak the item in Vanish especially if white. Tho possibly the Dr Beckmann Fats & Sauces one might work ok if sun cream is oil based? Dr Beckmann stain removers are great though, I’ve used a variety of them on sons shirts who seems to get covered in some weird & wonderful things. Good luck & sorry not to be more help.

Is it ok to use on clothes

We used it successfully on a white table cloth - but whatever you do, the fabric has to be able to be put into very hot water.

Does it remove orange stains

Yes it does. Tho I tend to apply it, let it sit for a few mins before washing. If item is white I also let soak for a while first.

Can you use this on wollen garments please?

Sorry, I’ve not used on woollen garments, I’d try and soak the stain out before washing - or take to a dry cleaner if possible. Sorry not to be more helpful.
