‘Lovely’ is a vague and rather weak adjective. It can be used positively and negatively (as sarcasm). ‘In a lovely way’ is something I’d never say, because it would be nearly meaningless. ‘Lovingly’ is an adverb but it refers to actual love, so has a different meaning. A. Tina called in sick again. B. Lovely. (Said with sarcasm. B is unhappy) You have a lovely home. (It’s nice.) She touched me lovingly. (In a way that expressed her love for me. You can’t replace that with ‘in a lovely way’. )

Hi Sofiyaaa, No, lovely cannot be an adverb. It's one of those rare words ending in "-ly" that can't be. And yes, those degrees of lovely are correct.

You'd have to use an adverbial phrase such as "in a lovely way", "in a lovely manner", or (depending on the particular context) a more specific adverbial phrase such as "with a lovely turn of phrase" (for how someone articulates a point). To make these phrases comparative, you can use lovelier or more lovely, and loveliest or most lovely. The degree of emotional resonance of "lovely" depends on context, precise phrasing and (in the spoken language) tone.

No. For adverbs, we have "lovingly" and "lovably". Look up their definitions to see how different they are. To answer the other question, read the poem by A. E. Housman, "Loveliest of trees, the cherry now". "Lovely" is a lovely adjective. By all means, use it a lot.

What do you want to convey? Lovingly is a nice adverb.
