I was just wondering when to use words such as hoor, wel, toch, etc. and where to put them in a sentence. If I'm correct, can't wel negate a negated sentence or something like that?; e.g. hij kan met ons niet meegaan, nee hij kan wel met ons meegaan. I know someone asked about this before, but it wasn't really explained.
In addition to the ones posted already, this is a good resource: https://zichtbaarnederlands.nl/zn/bijwoord-modale_partikels.php?taal=en
Maybe these websites are helpfull?
I am not a linguist. But as a Dutch native speaker I suggest a few corrections in your example sentence:
Hij kan niet met ons meegaan. Nee, hij kan wél met ons meegaan.
The word 'hoor' is almost always said at the end of sentence. It means something like "do you hear." For example: Jij gaat met mij mee, hoor! Translated: You are going with me, do you hear! It's used to put emphasis on a sentence or to convey understanding. 'Toch' is used in a similar manner, although it has a different meaning and you can use it after a verb or like 'hoor' at the very end of the sentence. For example: Jij gaat toch met mij mee? Translated: You are going with me, aren't you? Another example: Hij heeft nog een zus, toch? He has another sister, doesn't he? 'Wel' is also used to emphasize something, as in the sentence you posted. Hij kan niet met ons meegaan. He cannot come with us. Nee hij kan wel met ons meegaan. No he CAN come with us. There are many more such words used in everyday Dutch. They are called modal particles. Here's some more information on some of those words: http://www.dutchgrammar.com/forum/viewtopic.php?t=113 and http://www.dutchgrammar.com/forum/viewtopic.php?t=213
