    They look like scale insects

    Can they be left alone? Or will they damage the tree ?

    Large trees and shrubs can tolerate them but they can be damaging to smaller specimens.  Some are specific to certain types of tree - do you know what tree it is?

    That size tree looks quite manageable for you to remove the scale insects.  Try using a stiff brush to get at the larger trunk areas. I don’t think it will kill your tree. Maybe take a photo a bit closer so we can see the leaves. Was there any blossoms on it earlier this year?

    No no it’s not a blossom

    Looks like a young Lime Tree, Tilia Cordata possibly. Being so young, try to scrub/wash them off the branches. You will not get at all of them, but you will have lowered the amount. I think your tree will be fine. Make sure it gets watered well in the warmer months.

    I agree, best to scrape or brush them off with a stiff plastic scraper or brush on a young tree like that.  Slightly soapy water helps.  Do it asap because they will be laying eggs which hatch around June and the nymphs (sometimes called 'crawlers') are much more mobile and will move to fresh new growth before settling down to a permanent position and grow into what you are seeing.   If you see any with white 'fluff' at one end, those are the eggs in a protective waxy coating.
