Absolutely.

extremely rarely.

> Many words that mean completely different things are spelled the same

Homographs are rarely a problem precisely because they generally mean completely different things. Inelegant, sure.

> Many concepts are referred to by severaal different words, typically imported from different languages, and carrying different connotations.

Mostly true, but the richness of English vocabulary is the exact opposite of a problem. When you need to distinguish between shades of meaning, having more words available is useful. English doesn't have the problems of using the same word for 'high' and 'tall'; or for 'pasta', 'paste', and 'dough'; or for 'pen' and 'feather'. Loneliness and solitude really are distinguishable states.
