It isn't normal to use 'walk' as a transitive verb with an object, other than when we're talking about 'walking a dog' ( ie talking a dog for a walk). If you walk a person (+ a preposition or adverb) it suggests that you are maybe leading a person in a certain direction, or forcing them to walk. For example, if someone were extremely drunk and you tried to sober them up, you might say something like 'I took him by the arm and walked him round the park' ie forced him to walk. You might say something like 'I'll walk you to the door', meaning to accompany someone to the door when they're leaving. A woman getting married might talk about her father walking her up the aisle of the church, with the same meaning. The examples you give above are fairly unusual, though, and I can't think of any situations where it would be natural to use them.

To supplement Su.Ki. 's already excellent answer, here is definition 2 of "walk" from the Oxford Dictionary, with examples: QUOTE [WITH OBJECT AND ADVERBIAL OF DIRECTION] Guide, accompany, or escort (someone) on foot: "he walked her home to her door" (figurative) "a meeting to walk parents through the complaint process" UNQUOTE In Hollywood, or at society functions in the major capitals of the world, single lady celebrities (stars or society women, especially wealthy widows or divorcees) sometimes make arrangements to have suitable walkers walk them into an event (while sometimes the paparazzi shoot their photographs by the entrance). There have been well-known "walkers" (the males) throughout the past decades. "Would you like to walk me in?" is also a great pick-up line for a lady to use when going from the cocktail area into the dining room at a big party, or even at a house party in a big country house, especially when the target male is much younger.

One example of "walking someone in" is when access to an eating/drinking establishment, party or event is restricted. To "walk someone in" is to use one's privileged status to help someone else gain access. So... if you are the good friend of someone who is having a party, you might offer to "walk them in" so that they can get past the long line of invited guests. Or, if you are manager of an eating/drinking establishment and see a celebrity VIP driving up to the front door, you might rush out to "walk them in". After all, you wouldn't want them having to wait in line with the hoi-polloi. And, finally, a more grim example. It is standard procedure in the U.S. for a member of the clergy to offer to "walk a condemned prisoner" into the execution chamber. Sorry... I know this practice is considered barbaric by many in Europe.
