Certainly is not a verb, it's an adverb; a verb is something that you do (an action) such as jump, kick, run, glide, fall, hit, etc.
i think there is no verb form but you can add will to make it a verb just like "certainly will"
A verb is an action. How is not a verb, if that was what you were asking
The verb forms are access, accesses, accessing, accessed. The verb access is an action verb (a verb for an act).
The auxiliary verb can is the closest verb to the noun ability.
The word bit is not a regular verb. It can be either a noun or a verb, and as a verb, it is an irregular form of the verb to bite.

Yes is most certainly is.
Yes. You answer to me.
It can be a verb or a noun. As a verb: "I challenge you to show evidence to back up your assertion." As a noun: "Finding a job in today's economy is certainly a challenge."
No, furious is not a verb. It's an adjective.
No. A phrase you are looking for would be posed as a question.
A noun functions as the subject of a sentence or a clause, and as the object of a verb or a preposition.Examples:The next right will take you to the station. (subject of the sentence)It is most certainly my right to refuse to answer. (direct object of the verb 'is')
It may technically be a sentence because it contains a subject 'you' and a verb 'are'; but it certainly leaves a lot to be desired.
Running can certainly be a noun. It depends on how it is used. If you say "Running is my favorite sport," then the word running is used as a noun. If you say "I was running away from trouble," then the word running is used as a verb.
No, it can be used as either a noun or a verb.
ANSWER 'Want' is certainly used as a verb, for example, 'I want a cookie'. I think your question is: Can we use 'want' in a continuous tense? (For example, *'I am wanting a cookie'). We don't usually use a verb like want (a 'stative verb') in a continuous tense, though native speakers may do so occasionally to stress the temporary nature of the action. It's also more common in some dialects, like Scottish Highland English.
You certainly can use a helping verb, but it depends on the tense. If it's a simple past tense, you don't need one: Who ate my sandwich? Who took my pen? But if you are using a past perfect tense, the helping verb is necessary, to show an action that happened earlier in the past: Who has seen this movie? Who has read the chapter? Other examples of interrogative sentences with who asking the question but no helping verb: Who is Alice? Who are you? Who was the one? Who has the answer?
